Rezumat

The paper presents the results of mathematical modeling of the process of the squib charge blast and cumulative jet formation. The influence of the squib and the liner shapes as well as the impact of liner material, its thickness and the type of explosive on speed and energy of cumulative jet was investigated. The generated cumulative jet forms a perforation in the metal pipe and cement sheath, which is formed during well drilling with further plugging-back. The use of squibs for oil reservoir secondary drilling-in allows creating a high–quality hydrodynamic connection well-reservoir and maintaining a stable inflow to the well.
